TRANSMISSION AND DISTRIBUTION 
During the last five years, considerable attention has been given 
to the expansion of distributing systems and the extension of high- 
tension lines with the result that at present there are over 5,000 kilo- 
meters of cables carrying voltages of 10,000 volts and over. The 
total distances connected by these cables amounts to over 1,000 
kilometers, of which about 15 per cent is located in the Outer 
Possessions. 
West Java.—-The greatest development in this direction has taken 
place in west Java and has been carried out almost entirely by the 
Netherland East Indies Government. The outstanding distribution 
system in this area is the 70,000-volt line that transmits the output of 
the two great water-power stations, Oebroeg and Kratjak, to the 
metropolitan district of Batavia, Weltevreden, and Meester Cornelis, 
through substations at Buitenzorg and Depok. About 710 kilo- 
meters of 70-millimeter copper cable is used in this 118-kilometer 
line. Other important systems in West Java are the following:

The N. I. G. M. and the G. E. B. E. O., the two public-utility 
companies marketing electric current in west, J ava, have standardized 
the following currents for high and low tensions distribution in their 
respective areas. 
N. I. G. M., for high tension: 12,000 (volts); 7,000, 6,000, 2,000. For low 
tension: 440 (volts), 220/127, 110. ] 
G. E. B. E. O., for high tension: 30,000 (volts), 25,000, 6,000. For low tension: 
220/127 (volts), 190/110. 
Central Java.—There are no outstanding distributing systems in 
central Java, the longest high-voltage transmission line being only 
about 30 kilometers in lencth. They are listed below:
